There are some catfish species that get gargantuan. Like the wels catfish. Don't wanna mess with that bugger, I think it gets bigger than me!

Never did receive a reply from Marineland about the faulty bio-wheel in Sparky's Marineland Emperor 400. He's only getting half the filtration from that filter right now. Thank goodness the Fluval 405 is rated for up to 100gals.

Gah, that's sad! I have two tanks with those weird biowheels in them. . . and while mine have never done anything to make me mistrust them - I DO! I'm just not so sure about that form of filtration - even though the tanks they run in are fine! Hopefully they get back in touch and all is well :)

Yeah, some part is missing in the little notch where the biowheel sits and rotates, so this one wheel won't spin. The other one does. I think the only way to fix this is for them to send me a new filter because it's such a weird part to be missing. I don't think it can be repaired or replaced.

That sucks. When I had 5 goldfish in a 10 gallon (pet store advice, and I thought 2 gallon a fish was a lot) the filter was so clogged it stopped working. It was so gross. I got my mom to clean it :P
Hopefully they get back to you. That must be such a pain.

Today is day one of Sparky's new "every other day" feeding regimen. He was waiting in his typical corner when I went out there, bobbing like a log. How disappointed he must be. :( I'm sorry, Sparky, it's for your own pudgy good! *hides pellet bag*

I saw on TV today some type of cat fish.. IT WAS FRIGGING SCARY. HUGE. Not the average cat fish.. i guess it was like.. a cousin of the cat fish mixed with a shark or something xD SCARY.

Actually some of the largest freshwater fish in the world are catfishes. Sparky comes from a long line of chubby fish! The biggest fish that has been verified was a mekong giant catfish that weighed in at 646 pounds (293 kilograms) and was nine feet long (2.7 meters).

Then there are also the goonch (Bagarius yarrelli), piraiba (Brachyplatystoma spp), and redtailed catfish (which is sometimes sold in the aquarium trade grr) on top of the wels catfish. After seeing his cousins, better keep an eye on Sparky's weight!
